Senior Fullstack Engineer

Designing and shipping digital products with AI built in — from architecture to production.

Product-minded Senior Fullstack Engineer, taking full ownership of the product — from resilient architecture to AI features running in production.

My specialization

End-to-End Architecture & Fullstack Engineering

The result: a product whose architecture doesn't buckle as load or the team grows.

  • Business logic via DDD, scalable UI via FSD
  • Cross-platform desktop clients with Tauri (Rust)
  • APIs and integrations with NestJS

High-Velocity Product Delivery

The result: a working MVP, shipped fast, without cutting corners on code quality.

  • Development and testing accelerated by AI agent orchestration (Claude Code)
  • Dockerized from day one, ready to scale
  • Time-to-market cut dramatically for new features

Intelligence Layer & AI Integration

The result: AI that solves a job inside the product — not a chat widget bolted on the side.

  • Custom LLM pipelines and semantic search (pgvector)
  • LLM features inside the product: answer grading, content generation and parsing
  • AI embedded into business logic, not bolted on as a widget

solo-built SaaS products

Chronum (time tracking and invoicing for freelancers, real-time cloud sync) is already live; next up is Mnemio (an AI-powered learning platform with custom flashcards and decks). Both built solo, from architecture to release.

Behind the Code

About me

Nik Bogachenkov.

For over 7 years, I've been building production-proven software, helping startups and product teams scale from raw concepts to resilient digital ecosystems.

My journey started deep in the frontend ecosystem, where I often operated as the sole engineer responsible for the entire client-side architecture of high-load platforms. This naturally evolved into comprehensive Fullstack engineering. I realized I deliver the highest impact when I own the technical side of a product end-to-end: from business logic on the backend to scalable interface architecture on the client.

Currently, I focus on the intersection of product engineering and AI innovation. Building and deploying my own products—the Chronum SaaS ecosystem and the Mnemio educational platform—has allowed me to put custom LLM pipelines and vector-based semantic search to work inside real business logic.

I take full ownership of the product's performance, user experience, and architecture, ensuring it's built to scale alongside your business.
